Abstract:
We report a 12.2 W pulsed TEM(00) output from Q-switched quasi-concentric laser resonator with line-shaped end-pumping profile, with the repetition rate of 30 kHz and optical-optical efficiency of 27.1%. The laser output mode is symmetrized in two directions in terms of beam quality, waist radius, and waist position.
